Specifying the URL Type

The Ember router has four options to manage your application's URL: history,
which uses the HTML5 History API; hash, which uses anchor-based URLs; auto,
which uses history if supported by the user's browser, and falls back to
hash otherwise; and none, which doesn't update the URL. By default, Ember
CLI configures the router to use auto. You can change this option in
config/environment.js under ENV.locationType.

history

When using history, Ember uses the browser's
history API to produce URLs with a structure like
/posts/new.

Given the following router, entering /posts/new will take you to the posts.new
route.

Keep in mind that your server must serve the Ember app from all the URLs defined in your
Router.map function. In other words, if your user directly navigates to
/posts/new, your server must be configured to serve your Ember app in
response.

hash

The hash option uses the URL's anchor to load the starting state of your
application and will keep it in sync as you move around. At present, this relies
on a hashchange event existing in the browser.

In the router example above, entering /#/posts/new will take you to the posts.new
route.

none

Finally, if you don't want the browser's URL to interact with your application
at all, you can disable the location API entirely by setting ENV.locationType
to none. This is useful for
testing, or when you don't want Ember to muck with the URL (for example when you embed your
application in a larger page).
